Problems with wormholes which involve arbitrarily small amounts of exotic matter
C. J. Fewster, T. A. Roman
A quantum inequality bound on the expectation value of the null-contracted stress tensor in an arbitrary Hadamard state is used to obtain constraints on the geometries of traversab…

On wormholes with arbitrarily small quantities of exotic matter
C. J. Fewster, T. A. Roman
Recently several models of traversable wormholes have been proposed which require only arbitrarily small amounts of negative energy to hold them open against self-collapse. If the…

Minkowski Vacuum Stress Tensor Fluctuations
L. H. Ford, Thomas A. Roman
We study the fluctuations of the stress tensor for a massless scalar field in two and four-dimensional Minkowski spacetime in the vacuum state. Covariant expressions for the stress…
